What makes a light full spectrum?
Full spectrum fluorescent lighting uses a mix of phosphors in order to reach wider ranges of the Kelvin color temperature scale. They appear much “whiter” and closer to daylight than typical fluorescent lamps. The lamps look white when unlit, similar to typical fluorescent lamps.
Does full spectrum light include UV?
Full spectrum light bulbs are made to try to imitate natural sunlight, and like sunlight, they also produce UV rays. Typically full spectrum lamps have a Color Rendering Index (CRI) of 90 or above (100 is actual outdoor light) and a kelvin temperature of 5,000 or above.
How do you know if a light is full spectrum?
To be full spectrum, the light should emit all the wavelengths of light like a rainbow and in the same proportion as natural sunshine. The multiple wavelengths combine into white light. If just some of the wavelengths are present, the light has a partial or distorted spectrum.

What is full spectrum light?
Simulated full spectrum light is color-corrected light that operates in the range of 400 to 800 nanometers. This light will simulate the optical brilliance of outdoor light at noontime. This light can be measured by two numbers, CRI (Color Rendering Index) and Kelvin Temperature or (Degrees Kelvin). The secret to full spectrum light and optically balanced light is how close you can get to the optics of natural light. The Sun at noon has a natural color temp of 100 CRI and between 5000 and 5500 degrees Kelvin at noon time. Both CRI and Kelvin are important for the simulation sunlight.

Why is full spectrum lighting important?
Full-spectrum lighting is also very popular with gardeners, especially green-thumbed people trying to encourage plant life to thrive indoors. The proper full-spectrum lighting can help plants grow all year and even bloom in the winter. This additional growing time is possible because full-spectrum lights can produce the right color temperature to encourage photosynthesis, making for effective indoor growing operations.

Why do people prefer natural light?
Other research shows that people tend to prefer natural lighting instead of electrical lights, which could reflect a psychological association with nature that produces a positive effect. The positives created by daylight, according to some research, might improve people’s moods and motivate them more. And full-spectrum light sources provide that association with natural sunlight.
What is the full spectrum of light?
Full spectrum typically refers to the completeness of a light source's spectral energy, particularly when compared to natural light sources such as natural daylight. The exact spectral composition of a light source can only be determined by specialized photometric equipment, such as a spectrometer.

Does a full spectrum product contain all the same molecules as a plant?
Conceptually it’s simple — to leverage the concept of the entourage effect, a full spectrum product should contain all the same molecules as the plant. The problem is the plant contains hundreds of molecules that have varying chemical characteristics and any extraction process is going to lose some or many of the bioactive molecules found in the source ingredients.

Overview
Full-spectrum light is light that covers the electromagnetic spectrum from infrared to near-ultraviolet, or all wavelengths that are useful to plant or animal life; in particular, sunlight is considered full spectrum, even though the solar spectral distribution reaching Earth changes with time of day, latitude, and atmospheric conditions.
"Full-spectrum" is not a technical term when applied to an electrical light bulb. Rather, it implies t…
Measurement
Color temperature and Color Rendering Index (CRI) are the standards for measuring light. There is no technical definition of "full-spectrum" so it cannot be measured. To compare "full-spectrum" sources requires direct comparison of spectral distribution.
The emission spectrum of a light source varies depending on the light generati…
Use in art and in color matching
Ideally, during the day, an art studio (in the northern hemisphere) should be lit with northern sunlight, because it is considered more neutral and diffused than the direct, "yellowish" quality of southern sunlight. Since many artists' studios lack north-facing windows, full-spectrum lamps are sometimes used to approximate such light. Full-spectrum fluorescent lamps are also used by color scientists, color matchers in paint stores and quilters and others working with fabrics or yarn whe…
Use in aquariums
Full spectrum lighting is used both for tropical and marine fish as well as many other aquatic pets. The use of full spectrum lighting assists aquarium plants to grow and aids in the health of the fish and the tank as a whole. While plants have adapted to the reception of real sunlight, full spectrum light bulbs often mimic the emphasis of wavelengths of sunlight enough that plants are stimulated to grow. Full spectrum lighting also enhances the natural coloration of fish, plants an…
Use in gardening
Gardening under lights keeps plants blooming almost year-round, for a wintertime harvest. Grow lights are specifically intended to support plant growth, although with varying degrees of success and energy efficiency. Some plants grow better when given more of a certain color light, due to the mechanism of photosynthesis. Specifically more blue wavelengths enhance vegetative growth and development, while the addition of increasing amounts of red light enhances budding, flowe…
Use in seasonal affective disorder
In recent years, full-spectrum lighting has been used in the treatment of seasonal affective disorder (SAD) through the use of "light boxes" that mimic natural sunlight, which may not be available in some areas during the winter months. Light is an environmental stimulus for regulating circadian cycles.
Lightbox therapy, otherwise known as phototherapy, is a recognized modality for depression (su…
